Police are also investigating a car blaze, after a Seat Ibiza was torched in Montgomery Avenue, in Gallowhill, on Saturday night.

It’s the second car to be gutted by fire in the town after fire crews tackled another arson attack in Foxbar Road, where a Vauxhall Insignia was targeted by firebugs on Tuesday night.

Frightened pensioner Janet Robinson, who lives in the Springbank Sheltered Housing Complex just meters from the construction site inferno, told the Paisley Daily Express how she alerted the fire service to the blaze.

The 76-year-old said: “I was in my bed and I heard a noise and thought it was maybe fireworks so I went to look outside.

“I saw what I thought was a light coming from the building opposite then it just burst into flames. It went up so fast.”
